Question

choose the correct option:
The condition that is most appropriate for electroplating with nickel.
1. Electrolyte is molten copper sulphate 2.Anode should be made of impure nickel plate
3. Alternating current is used
4. Periodic replacement of cathode is needed.​

Answer 1

Answer:

nickel sulfate

Nickel electroplating is a technique in which a thin layer of nickel is electroplated on a metal. In this process nickel sulfate is used as an electrolyte, an article to be electroplated is placed at cathode and a block of nickel metal is used as

Answer 2

The correct option is that the alternating current is used.

• Electroless nickel plating involves the usage of chemical nickel plating baths due to which is also known as autocatalytic or chemical nickel plating. Nickel ions Ni2+ are present in the aqueous solution of nickel sulphate is involved in the process of electroplating.
• Here, an Aqueous solution of nickel sulphate is used as an electrolyte. Block of nickel metal and Article such as nail that is to be electroplated are used as anode and cathode respectively.
• The reaction at Cathode is as follow

          $Ni^{2+}$$+ 2^{e-}$ → $Ni(s)$

• The reaction at the anode is as follow:

              $Ni(s) - 2^{e-}$ → $Ni^{2+}$

• The Block of the nickel atom that is used as anode must be pure.
• An alternating current is used in the accomplishment of the electroplating process to deposit the metal on the surface of the cathode by dissolving it

Hence, the correct option is 3.
